Summary

libarchive security update

Details

is an open-source BSD-licensed C programming library that provides streaming access to a variety of different archive formats, including tar, cpio, pax, zip, and ISO9660 images. The distribution also includes bsdtar and bsdcpio, full-featured implementations of tar and cpio that use .

Security Fix(es):

A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service.(CVE-2026-14164)
